Hello, Just wondering, is this feature available in apache Isis 1.10.0? I tried to follow a link, but it issues an error "not a string". It would help a lot with my client application if I can eagerly load links (parent - child ) just like in the video.
This link works ok and shows value.href values with its link: http://localhost:8080/restful/objects/simple.BusinessLocation/1/collections/itemBusinessLocations The this one: http://localhost:8080/restful/objects/simple.BusinessLocation/1/collections/itemBusinessLocations?x-ro-follow-links=value.href issues: { className: "java.lang.IllegalArgumentException", message: "is
